Comparison of the Efficacy of different Doses of Glucocorticoid Nasal Spray Combined with Loratadine in the Treatment of Rhinitis in Children: A Randomized Clinical Trial
,
Abstract
Pediatric rhinitis is a common recurrent disorder that may progress to asthma or sinusitis in severe cases. This study aimed to compare the efficacy of different doses of glucocorticoid nasal spray combined with loratadine for rhinitis in children, and provide evidence for optimizing clinical treatment.
A total of 150 children with rhinitis admitted from June 2022 to June 2024 were divided into three groups: group I (low-dose group, n=50), group II (medium-dose group, n=50), and group III (high-dose group, n=50). Patients in all three groups were treated with a glucocorticoid nasal spray with loratadine combined with antihistamines. The immune function, serum inflammatory factor level, quantitative Lund-Kennedy score by nasal endoscopy, nasal symptom score, Quality of Life Questionnaire (RQLQ) scores, clinical efficacy, incidence of adverse events, and treatment compliance were assessed.
Post-treatment, all indices improved in the three groups. The percentages of CD4+ and CD8+ T cells, IL-10 content, and clinical efficacy in groups II and III were significantly higher than those in group I, while the immunoglobulin E (IgE), IL-6 and IL-17 content, the quantitative Lund-Kennedy score of nasal endoscopy, the children’s nasal symptom scores, the RQLQ scores, and the incidence rate of adverse events were below in group I. No significant differences were found between groups II and III in all indices, nor in treatment compliance across the three groups.
Loratadine combined with a glucocorticoid nasal spray therapy effectively improves clinical outcomes, inflammation, immune function, symptoms, and quality of life in rhinitis in children, with high clinical application value.
